TO ALL WHOM IT MAY CONCERN:

Be it known that I, JOHN VAN GAASBEEK, of Mount Vernon, in the county ofillescliester, and State of New York, have invented certain new anduseful improvements in Apparatus for Raising the Bents of Buildings; andI do hereby declare that the following is a full, clear, and exactdescription of the same, reference being had to the accompanyingdrawings, making a portion of this specification, in which- Figure l isa side view 'of an apparatus, constructed according to my invention,represented as applied to the sill and bent ofthe frame of a building,previous to raising the bent into a vertical position. 'l

Figure 2 is a similar side view of the saine, with the bent shown in anupright position.

Figure 3 is a side View-taken at right angles to figs. 1 and 2, andshowing the apparatus applied to the two posts of a bent, with thelatter in an upright position.

Figure 4 is a, side View, corresponding to iigsl and 2, but showing aslight inodiiication of my invention.

Figure 2 is a side View of the same, taken at right angles to iig. 4,but of the side opposite that shown in hg. 3. I

Similar letters of referenceindicate corresponding parts in both gures.'

The object of this invention is to enable the operation of raising thebents of the framework of buildings from a horizontal to their verticalposition in the said framework, to be performed with a much less outlayof time and labor than by the ordinary means and appliances, and to thisend the invention consists in two flange plates, hinged or pivotedtogether, and furnished with suitable means for being attached, onc tothe sill'ot` the framework, and the other to the adjacent post of thebent, whereby one set of the apparatus being applied to each of thepostsot' the bent, the lower ends ofthe said posts are securely held inproper position and prevented from slipping while the bent is beingraised or turned upward into its vertical position in the aforesaidframework, thus efectually securing the desired object. The inventionfurther consists in a novel means whereby the apparatus is adapted touse in raising bents differing widely in the size or 'thicknessof theirposts; and, furthermore in a novel means whereby the position of theapparatus may be so gauged or adjusted as to insure the proper and easyentrance of` the tenen formed on the post to which-it is attached, intothe mortise formed in the corresponding sill.

To enable other-s to understand the construction and operation of myinvention l will proceed to describe it with reference to the drawings.

.A and B represent two strong metallic plates, each of which isfurnished at its side and near one end withtwo lugs or ears, situated ina longitudinal position tnereon; the lugs of the plate A being marked ain the drawings, whil'c those of the plate B are indicated at of Thelugs b of the plate B are placed between the corresponding lugs d' oftheplate A, and areconnected therewith by a transverse pin or pivot, a,which passes through suitable holes in the several lugs, and thus pivotsor hinges the two plates together. Each oi' the plates A B has formedupon one of its lateral edges a tlanch, l, which is situated in aposition transverse to the plate, as indicated more clearly in figs. l,2, and 4. In addition to its iia-nch, Z, the pla-tc B has formed uponthe suine lateral edge as the said Hauch an ear or extension, d, inwhich is formed a long slot, cZ, and at its opposite lateral edge withasimilar but shorter ear, e, in which is formed a hole of any suitablesize. The extremity a* ot' the plate A, near which the lugs ft of thesaid plate are formed, is so situated with reference to the innersurface ot" the plate B, that when the said plate is. in a verticalposition the aforesaid end ot' the plate A will be in line with thesurface Erst mentioned of the plate B, whereby the said extremity oi'the plate A is enabled to act as a guide or gauge, by which the positionof the apparatus may be so adjusted that the tenen of the post of thebont will be brought immediately over the mortise in the adjacent sill,as will be hereinafter fully explained. The plate A is placed upon theupper side of the sill, which is shown at'C, with its extremity, ai,situated just at the edge of the mortise` shown in dotted lines at o, infigs. l, 2, and 4, and with its ilanch b in close Contact with the outerside of the said sill, and is secured thereto by means ot a strongscrew, ci", which passes through a suitable hole formed vertically inthe said plate, and is screwed firmly into the sill. This being done,the plate B is turned back into a horizontal position over the plate A,as shown in iig. 1.; and the adjacent post-amerked D in the drawings-piothe horizontal bent is placed thereon with the tlanch b of the aforesaidplate B fitted to its outer side. The post is then securely clamped tothe plate B by means of a chain or band, E, one end of which is attachedto an eye-bolt which is secured in thehole hereinbefore mentioned, ofthe ear e, and the opposite end of which is attached to a similarboltpassing through the slot d of the other ear d; the said clamping .chainbeing tightened to the required degree by means of suitable nuts,screwed upon the outer ends of the aforesaid eye-bolts. The two outsideposts of the-bent being connected cach with the adjacent sill by a setofthe apparatus, the bert is raised and turned upward inte a verticalposition, the pivots a, ofthe plates B, holding the lower ends of thepost from slipping` and at the same time freely permitting the required.upward movement ofthe bent. Inasinuch as the inner surface of thelanches of oneplate is lcoincident with the corresponding surface ofthat of the other plate, it follows that the outcrniost lateral surfacesofthe post and sill will be in line with each other asvthe bent isbrought into its upright position; so that by this means any lateraldisplacement of the tenen d* of the posts with reference tothe mortisesin the sills is eiectually provided against. And inasmuch as the innersurface of each of `the plates B, when in a vertical position, lineswith the end of the contiguous mortise, it follows that. the tenen ofthe post is brought exactly over the mortise, so that when the clampingchain or band Ei s ;looscned the weight of the bent will cause the tenonto descend into the mortisc without further'trouble. In order to avoid atoo sudden strain upon the lugs a ofthe plate A,"when the bent is thusbrought into an upright position, the holes in the said lugs, throughwhich the pin or pivot a is passed, may be somewhat elongated, as shownmore clearly in l'ig's. l, f2, and 4. Inasmuch as the slot d allows theeye-bolts, to which the ends of the clamping chain E.

are attached, to be placed at any desired distance apart, it followsthat the plate B may be clamped upon a post of any desired size, thusenabling the apparatus to be employed in raising bents differing in thewidth of their posts. As a means of clamping the plate B to the post,equivalent to that just herein described, a bar, constructed with a slotin one end corresponding in shape and size with that of the ear eZ, andwith a helein the other end answering to that in the ear-e, may beplaced transversely upon that side of the post opposite that at whichthe said plate B is situated, and connected with the latter by means ofbolts passing through the hole and slot of the said bar, and throughthose of the ears d e, as shown in figs. 4 and 5, the said bolts beingtightened by means of nuts, in substantially the same manner as theeye-bolts hereinbefore described.

Having thus fully described my invention, I do not claim a timber clampfor the purpose specified 71er se, as such apparatus has been usedbefore; but what I claim as new, and desire to secure by Letters-Patent, is-

1. The two hanged plates A B, pivoted together and furnished withsuitable appliances whereby they may be attached to the post of a bentand to the sill, in the Amanner herein set forth for the purposespecied.

Q. The arrangement 0i' the extremity a of the plate A, with reference tothe inner surface of the plate B, and of the tlanched sides of saidplates, that the said extremity and sides shall serve as guides fordirecting the tenen on the post into the mortise in the sill,substantially as set forth. i

3. The construction of the plate B, with the slotted ear d, lwhereby theclamping chain F, or its equivalent, may bc adjusted to clamp the plateB to posts of any desired size, substantially as herein set forth.
